HANDLE FOR UTENSIIJS WHICH ARE SUBJECTED TO HEAT.

Application led October 17, 191%.

To all 'Lo/tom t may concern.'

Be 1t known that I, Davie I. Gnnnnrson, a citizen of the United States,and a resident or' the borough of Brooklyn, city ofl convenienthandlefor utensils, which will' remain sufficiently cool, or be self cooling,so that the handle may be grasped without danger of burning the hands,even though the article to which the handle is attached is placed on ornear a source of heat.

irons, stove litters, coffee pots, furnace doors and for many otherdevices which are more or less subjected to heat. When handles have beenpermanently attached to such articles they have been more or lesssubjected to heat with the utensil itself, either by the direct actionof the heat, or by reason of conduction through the materials of whichthe articles and handles are made. Handles or holders which are intendedto be detached from the utensils While the latter are subj ected to heatand then attached to the utensil or used to grasp the same, are notaltogether satisfactory because, as generally constructed, such handlesabsorb heat from the utensil after itis removed from the source of heat,to an undesirable extent. The object of the present device is to providea handle or grip which will not become too hot for the hands even thoughthe utensil itself is subjected to heat. The handle is so made that thehand is protected by insulating material, such as asbestos, and the heatreceived by the handle directly and by conduction is rapidly radiated insuch a manner as not to uncomfortably affect the hands of the user. y

I have shown my invention adapted to different kinds of utensils; and Ihave shown it both as a separable or detachable member and also as alined part of the utensil. For instance, I have shown my improvements`embodied in a form which makes it convenient for attachment to sadSpecification of Letters Patent.

same in a form or forms in which the handle is made a fixed part of theutensil.

Fig. 7 is a plan view of the sheet from which the lifter is formed, and

Fig. S is a sectional view of my'improved handle adapted for coliee potsand the like.

In Figs. l to 3 I have shown a handle formed separately from the utensilin order thatit may be readily applied to articles now in use. Toillustrate the application of my invention I have shown an ordinary sadiron l having the fixed and bowed metal handle 2. In general practice itis customary to use a pad or holder in order to grasp this handle; andin order that the pad shall not become too heatedit must be removed fromthe iron while the latter is being heated. These holders are oftenmislaid, or they become uncomfortably hot from contact with the ironhandle. The handle herein shown, however, will remain suiliciently cool,even though attached to the iron while the latter is being heated. Y

In Fig. 3 I have shown the blank from which the handle is formed. Thisis preferably a sheet of metal 3 having, in the form shown in Figs. l to3, the angular extensions 4 at the several corners. This sheet isprovided with a number of projections 5 drawn or stamped from the sheet,thus leaving a number of apertures 6 therein. rI`hese projections areformed at various points on the plate, preferably at close intervalssubstantially throughout the surface of the ing material, preferablybefore itis bentrr into tubularV shape. l have shown the plate coveredwith an imperforate coat of insulating material Zv to form the grip. lprefer to use asbestos or a similar non-inllammable and heat insulatingmaterial for this purpose; and it may be attached to the plate underpressure while hot, using, silicate orV other material to retain theparts in pe rmanent bond.

The plate 3 yand the insulating grip are now bent around yto form atube, which is.` preferably `cylindrical throughout the greater portionof its length; and flaring at each end at the under portion. The flares8 permit the handle to conform to the bends 9 in the iron handle 2 andstill have the" othery portion of the handle remain cylin-y drical. Theenlarged diameters caused by. the flarescl also tend to keepthe hand inthe intermediate portionr l0 of.y the handle and prevent the lingersfrom coming into Contact withthe handle 2.

When the handle is bent around.v and securedl to the iron handle, asshown in Fig. l, thez projections 5, extend inward or toward. the middleof the cylindrical handle, and some.y ofy these contact withv the ironhandle 2 and keep the tubular handle spaced' therefrom. rlhis forms aheat radiating and a ventilating space ll between theviro'n han? V dleand the tubular handle, which opensv outwardly at each end of thelatter.

The stiffness of the metal of the tubular handle may serve to hold it inplace upon the iron handle,`bnt l` prefer toy provide binding bandswhich may be in the form'E of wiresl. passing around the Vtubulary han!dle and having their ends twisted together.

The tubular handle is preferably retained on the iron handlepermanently. When the iron is placed on the stove for heating, and'`.afterward when being used, the heat condueted by thev iron handle 2will have but little elfect upon the` tubular handle owing to thecomparatively limited Contact surface between.0 them.Y Such heat Vas mayreach the plate 3 *will` be very rapidly radiated therefrom, owing tothe lugs or project-ions 5 which extend into the radiating and coolingspace. There will, therefore, be almost an inappreciable amount of heatconducted to the asbestos covering 7 and such as may reach the interiorsurface thereof will not reach the hand of the user owing to the heatinsulating` nature of the asbestos.

lThe primary purpose of stamping the pro-V jections 5 from the sheet 3is to reduce the superoial area ofthe sheet and provide means for morerapidly radiating the heat therefrom.

ln Figs. 4 and 5 l have shown the improved handle constructed as apermanent part of vthe iron handle, as this form is preferable whereirons are to be supplied with my improvementsv when manufactured. In

this` forin a; 13 having. theshanksor strips ltateachnend, with anintermediatev plate l5, isprovidedwith,anumber of pro.-V

jections 5. These, are shown j in this. form of the-'device as beingarranged in pairs atY opposite sides ofthe apertures 6 ythis beingvain/1ere variation in form', from those pref'` viously described.l Inthisform'oftheghandle theinsulating material 7 forw covering the handlemay. be appliedto the sheet 13 before the latter is shaped. The Shanks14y are 'bent downward to form bowsl to icorre-i spondfwith the,similar. parts of the, ordis nary iron.V Theends ofE these bows are,fse-` ouredto'the iron. lrevious to this, however, the plateliscurvedaroundto form a tubular handle, entendingupwardly the top lineofthebows, assllQWn/in igl-` ln this; form, as in the previousone, thetubular, handle is hollow; thus providingan interior: heat radiatingspace. The ,heat will be ,radiated in thisform of devie the ,same

arm lSQthe latter having the tongue 19 and ears QOwhich serve for'engagingy the stove lidI in well known manner.4 llhe plate 17 isbentaround to formA aft'ubular handle 21'. This handle, as intheprevious forms, has the inwardly projecting kradiating members 5..stamped therefrom; and the imperforate insulating eoveringl 7. Y Theheat conducted by the arm 18 to the handle israpidlyradiatedfromtheprojeotions and passes outiof the ends of the tube; so that theexterior: surface Yof the asbestos willnotbeoome over? heated. A

ln7 Eig. 8 l have shown the invention applied to aoof'teepot or similarvessel. A22, representsthe wall. ofthe receptacle, from which extend theparallel arms 23.v Between the outeriendsof the latter therefis arrangeda tubular shell Qet of stamped metal havingthe inwardlyextendingradiating projections 5. The ends of the tube 24: are swaged at25 to firmly hold the handle between the arms 23. The insulatingcovering 7 surrounds the tube 24 and abuts against the arms 23.

In each form of the device a tubular body or shell is formed of stampedsheet metal with the inwardly extending radiating projections; and theshell is covered with the imperforate insulating material. This forms avery rapidly cooling handle which protects the hands.` The device isvery simple and inexpensive.

Having described my invention, what I claim is l. A handle for devicessubjected to heat, comprising a sheet of metal having an intermediateplate and oppositely extending arms, said arms being bent downwardly toform supports for attachment to a body and adapted to hold saidintermediate plate in spaced relation to the body, said intermediateplate being bent into a tube to provide an interior chamber open at theends, said plate having radiating projections extending laterallytherefrom.

2. A handle of the character described, comprising a shell formed ofsheet metal provided with projections stamped from the sheet and formingperforations in the sheet, said sheet being formed into tubular shapewith an interior chamber open at the ends, and with said radiatingprojections extending inward in the said chamber, and an imperforateexterior covering of asbestos or similar heat insulating material Jforsaid shell, and closing the apertures in said shell.

Signed at the city, county and State of New York, this 14th day ofOctober, 1913.
